Product Description

High capacity weight or spring loaded pressure relief valves that pipe away to a closed header system. Designed to work closer to a tank's MAWP, increasing productivity, reducing emissions and product evaporation

Features

  • Increased flow capacities reduce the required valve size and the corresponding connections and piping costs.
  • Fully open at 10% overpressure, enabling setting close to MAWP and minimizing tank emissions.
  • Large body for increased capacity providing high flow performance for full conformance to API2000/ISO28300.
  • Leakage rate of 0.5 scfh (0.015 Nm3 /hr) or less at 90% of setpoint.
  • Weight or spring loaded models available.
  • Choice of body materials.
  • Modular design enables all components to be removed and replaced in-situ for quicker, simpler maintenance.
  • Optional ‘all-weather’ coating prevents frozen condensate build-up and sticking of vital components in cold weather applications.
